To allwiwma't may concern:

Be it known that I, Anonrn Fnno WAL- 'r, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and

State of Ohio, have invented new and useful whic 1 utilized in building operations. More Improvements in Hoist Towers for Building Operations, of which .the[ following is a specification, the principle of the invention 2 means embodying my invention, the disclosed means, however, constituting but one of the various mechanical forms .m which the principle of my invention may be applled.

Referring to the annexed drawings, it will be noted that my improved tower consists of a plurality of telescoping rectangularsections, each consisting of corner an les and connecting braces and trusses. or the purposes of illustration, l have shown 4: of these sections, the same consisting of corner angles 1, 2, 3 and 4, respectively; trusses 5, 6, 7 and 8,. respectively; and braces 9, 10, 11 and 12, respectively. Secured adjacent the tops of the sections 1, 2 and 3 are plates 13, 14 and 15, respectively, upon upward extensions of which, 13', 14' and 15', are mounted sheaves 17, 18 and 19, respectively. Lifting cables 20 adapted to be wound on drums 21 by means of operating mechanisms 21' are secured at one end respectively by means of hooks 27 to plates 26 secured to the inner section 4, Figure 2. Secured adjacent the bottom of the sections 2 and 3 are sheaves 22 and 23 respectively. By my preferred method of erecting thetower, the. cable 20 00-0 crates with the sheaves 17, 18, 19, .22 an 23, and the sections-2, 3 and 4? are temporarily secured tomanner illustrated in Fi corners of the connecting evident that the winding operation of the Wei-{mechanisms 21' will, the sections bemg te escoped and connected as shown in Figure 25, result in the lifting of sections 2, 3 and 4: in the manner shown in Fi me 26 until the bottom of the section 2 15 adjacent the top of section 1. Sections 1 and 2 are then detachably secured together by means hereinafter fully described. Then, 0 amps 24 being removed, the continued operation of the power mechanisms '21 results in the lifting of sections 3 and st in. the re 27 until the bottom of section 3 is adjacent the top of section 2. Sections 2 and 3 are then detachably secured together. Clamps 25 are then removed and the continued operation of thepower mechanisms 21 results in the lifting of section t until its lower end is adjacent the to of section 3. Sections 3 and 4 are then etachably secured together.

Durin the erection guy ropes 31 secured to guy 0 amps 31 are utilized in any necessary and practicable manner. For the pur pose of securing sections 1 and 2, 2 and 3, and 3 and 4:, respectively, to etherthesections 2, 3 and 4 are provide with leg portions 29, hereinafter called s lice an les, plainly shown in Fi res 2 an 5, and 1t is the provision of t ese leg portions that makes sections 2, 3 and4 appear-"in Figures 1 and 2 to-be higher than section 1.

The sections are detachably secured to-' gether b means of bolts32, Figures 7, 8 and 9; he bolts 32 do not directly connect the sections 1 and 2, 2 and 3, and 3 and 4, but the innermost section, in each instance, is provided with a splice angle 29. and a filler 28 adapted to fill the space between the adjacent sections, said splice angles 29 and fillers 28 being permanently secured to the respective inner sections by means of countersunk rivets 30.

A modified form of section-connecting means is shown in Figures 10, 11 and 12, wherein the spacing members or filler-'28 are omitted and there is utilized in lieu thereof, bent splice-angles 29'. The last described. means obviates the necessity of countersinking the rivets 30' on the outside, saves weight and dispenses with the sharp means shown in Figures 7, 8 and 9.

eferrin to Figures 29 and 30, a modified metho of erection is therein diagrammatically illustrated, by means or which the innermost section 4 alone is first lifted, sections 1, 2 and 3 being temporarily fastened together by clamps, 36; clamps 36 are then removed and sections 3 and a are lifted, sections 1; and 4 2 being temporarily fastened togetherby clamps 3? than clamps 3% are me ias removed and sections 2, 3 and 4 are lifted.-

This method of erection does not give the stability obtainable by the method illustrated in Figures 25, 26, 27 and 28, nor allow for as efficient a use of the guys 31 as the preferred method.

Upon the erected tower, shown in Figures '13 and 14, are secured laterally extending brackets 40 forming supports for elevator ways comprised of the members 41 and 41', Figures 23 and 24. The members 41 are secured to the brackets 40 by means of the bolts 42, the members 41 being laterally extended to form an inner confined sliding surface 43 for an elevator 44. By means of bolts 45 and spacing members 47 and 48, guide shoes 49 adapted to slide upon the surfaces 43 are secured to the rear vertical frame member 46 of the elevator car 44. The latter is lifted and lowered by means of an elevator cable 50 adapted to play over an upper sheave 51 mounted upon the to of the tower section 4, said cable 50 exten ing down to and playing around a sheave 52, Figures 14 and 21, secured adjacent the bottom of the tower section 1 and then running to an engine (not shown) by means of which it is operated.

Referring to the form of tower shown in Figures 13 and 14, it will be noted that upon the side thereof, opposite the car 44, is provided a hopper 53, Figures 23 and 24, adapted to be fixed to the tower at any desired height by means of clamps 54. This hopper 53 is raised and lowered by means of a power cable 55 playing over an upper sheave 56 secured adjacent to the top of the tower section 4, the cable extending downwardly and laying around a lower sheave 57 secured adjacent the lower tower section 1, said cable then running to a winch (not shown) by means of w ich it is operated. This hopper 53 forms a support for a (1 18 tributor pipe 58, Figures 13 and 23, which is supported by an upper conlcal mouth 58 so as to be rotatable about its own axis.

It will be plainly seen in Figures 23 and 24 that means are provided for passing material from the car 44 to the distributor 58. The back wall 46 of the car 44 is formed with a gate 60 adapted, when open, to rest upon the end 61 of a trough 59. This gate can be closed by means of a lateral arm 62 provided at its outer end with a countercure ing means such as the an 10 64. When it is.

weight 62' and operated by means of an actuating bar 63. The end of trough 61 also will close the gate 60, if inadvertently the latter is left open when the car 44 commences to descend. A passage for material through the tower from the car 44 to the distributor 58 is. provided, by means of said trou h 59, the same being temporarily seand positioned by any suitable holddesired to change the helght of the hopper 53, the trough 59 is temporarily shoved upon the platform 44' of the car 44.

Referrin to Figures 15 and 16, it will be noted t at therein are shownelevator cars upon two sides of the tower. This renders it necessary to provide means for transferring material from an elevator to the distributor, difierent from the means shown in Figures 23 and 24. In Fi res 15 and 16 I show two troughs 59' adapted .to convey material'from the respective cars 44 to a common hopper7 6 disposed centrally er the tower and from which the material may be drawn through a discharge member 77 to a distributor (not shown) mounted upon one side of the tower between the cars 44. In Figure 17, two elevator cars 44 are shown in conjunction with a concrete mixer 78 disposed adjacent the bottom of the tower. The mixture of materials is furnished to .the hopper 70, whence they pass to the mixer 78 operated by the mechanism 79. Then the prepared mixture is discharged through a s out 7 O to either desired car 44. The spout 0' is rotatably mounted upon the side frame of the mixer 78 so that sald spout can be turned to discharge upon the platform of either of the cars 44.

Referring to Figure 18, one of the elevator cars is therein indicated as a platform 65 upon which to lift loads of brick 69, for nstance. By means of a suitably supported intermediate gang-way 66, the brick is deposited upon any'desired floor 68 of a building 67 It will be noted, of course, that the material is taken from the platform 65 at substantially the level of the floor u on which it is desired to dump the materia Referring toFigure 19, a use of my improved tower with booms 71 is therein disclosed. Operating cables 72 serve to raise and lower the outer ends of the booms, the same playing over sheaves 73, secured adacent the top of the tower; and operating cables 75 playing over sheavesSO secured adjacent the outer ends of the boom 71 serve to raise and lower the grab-hooks 74. I

of a height intermediate two successive multiples of a single section height can be erected and utilized for many purposes by simply holding the sections at the desired height by means of the cable 20, the sections in this event not being secured together by the usual splice angle. I

Referring to Figures 31 to 37 inclusive, amodified form of tower-erecting means istherein shown in which'a special derrick 81, styled a breast-derrick, is utillzed. This breast-derrick 81 is adapted to be detachably mounted upon the several tower sections 1, 2 and 3, all of the motions in this form oi apparatus bein shown as of the sameheight. The means vfiiich are utilized for mounting the breast-derrick 81 upon the several sections are the same means which are utilized for detachably connecting together the seyeral sections, when the tower is erected, sa d connecting means being, in each instance, n multiple so that said means can be in common for both purposes at the same time. This detail will now be fully described. The connecting means consists ofa series of bolts 82 and 83. Bolts 82 pass through a lower strengthening plate 84 disposed ad acent the bottom of the breast-derrick 81. It will be plainly seen in Figure 31, that ulleys 86 are mounted adjacent the top of t 0 breastderrick 81, over which pass an operating cable 85 adapted to be wound upon a drum 87 secured adjacent the lower end of the tower section 1, suitable power means 88 being provided! The operating cable 85 is furnished with a hook 89 adapted to engage the lower end 90 of the tower section 2 proper. it will be noted that the tower sec-. tion 2, for instance, is provided w1th bolt holes 82 adjacent the bottom thereof. These bolt holes 83' are adapted to align With; the upper two bolt holes of a spllce angle 91,

this splice angle having in addition two 1 lower oles which register with the holesof the upper two bolts 82 of the breast-derrick plate 84:, Fi re 32. It will be evident that, the breasterrick 81 having been manually lifted to the top of the tower section 1 and mounted thereon by means of bolts '82 and the operation of the power means 88 will result in the lifting of the tower sectlon 2. en the section 2 is raised sufliciently so that the bolt holes 82 will align with the upper holes in the splice angle 91 when the lower holes in this splice angle register with the holes of the upper two bolts 82, the bolts of the latter, as well as the lower adjacent bolt, are removed, and the plate 84 taken oil. The bolts 82 are then utilized to fasten the sections 1 and 2 together, the splice angle 91 and single bar llers 92 being utilized,

. Figures 36 and 37. This connection of the is erec sections 1 and 2 serves to hold the same together, after which the lowermost bolts 83 are removed, thus wholly freeing the breastderrick from the section 1. The breast-derrick is then manually lifted to the top of section 2 where it is again detachably mounted by means of the holes 82 and the foregoing operation repeated, whereby section 3 is mounted upon section 2. Then section 4 is lifted to the top of section 3, holes 82 bei utilized this time, and thus the tower assures B the means hereinbefore described, here ina ter claimed, and shown in the accompanying drawings, 1 am enabled to uickly and easily erect a tower adaptable or use in building operations, of suficient height adequately to serve all the necessities of telescopic secupon said guideway; and means for opeing said elevator car on said guideway.
